JNK Signaling in Skin Cancer Basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) represent the initial along with the second Basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) represent the first of BCC most common skin cancers [121,122]. In between 1976984 and 2000010, the all round incidence along with the second most typical skin cancers [121,122]. Among 1976984 and 2000010, the overall incidenceCells 2020, 9,9 ofand SCC was improved by 145 and 263 , respectively [123]. About three million circumstances of BCC and SCC were diagnosed in the US in 2019 [124,125]. Melanoma is definitely the fifth most typical cancer in males as well as the sixth most common cancer in females [126]. An estimate of 192,310 new instances of melanoma was diagnosed in the US in 2019, with about 50 of them being invasive [125,127]. Popular danger factors for skin cancer contain ultraviolet (UV), ionizing radiation, arsenic exposure, viral infection, and wounding [12832]. JNK, as a dominant responder of those environmental stimuli, plays paradoxical roles in cancer improvement with both oncogenic and tumor suppressor properties [133,134]. three.1. Differential Roles of JNK1 and JNK2 in SCC JNK activation is often observed in SCC [135,136]. Specifically, JNK2 phosphorylation is improved in SCC cell lines and tissues in comparison with regular keratinocytes and healthier skin samples, respectively [135,137]. Jnk2 deficient mice had been resistant to skin cancer development following induction by the DMBA (7,12-dimethylbenz[]anthracene)/TPA (12-O-tetradecanoylphorbol-13-acetate) two-stage carcinogenesis protocol, indicating that JNK2 functions as a promoter of skin cancer [138]. Regularly, when compared with WT mice, Mkk4 deficient mice displayed substantially decreased numbers of skin tumors following 20 weeks of DMBA/TPA treatment, which was attributed to decreased JNK2 activity [139]. In contrast to JNK2, JNK1 showed a tumor suppressor function. Jnk1 deficient mice displayed a higher papilloma incidence than that of wild-type mice [140]. In agreement with these findings, constitutively active MKK7 and MKK7-JNK2 fusion proteins, but not MKK7-JNK1, are able to cou.
